I read a few less than flattering reviews of In a Madman's World so I went in with low expectations, but that actually helped me because by the end I thought this was a decent well made low budget movie and biography of one of the country's worst serial killers Dean Corll
I can tell the director and writer Josh Vargas did a lot of research and put a lot of effort into accurately portraying Corll's biography. As a result Vargas brings vividly to life the graphic and awful nature of Corll's crimes, the boredom & poverty that existed in Houston's The Heights in the early 1970s & how Corll's unsuspecting victims were lured to their doom. Location settings throughout also gives the movie a lot of authenticity that help immerse you in
I have to say Joe Grisaffi does a brilliant job portraying the creepy Dean Corll, and Chris Binum gives a solid performance of accomplice and misfit Wayne Henley & Bobby Haworth does well as the wigged David Brooks. Yes, there are some rough edges with the script, but I don't think it's a huge deal or detracts from the theme.
Having read a lot about Corll over the years including Jack Olsen's The Man With The Candy, I liked In a Madman's World and anyone with an interest in true crime I recommend it.
